      Very helpful



      For small package the Knog Boomer lights pack quite a punch. Good value light.

      When I first started searching for a pair of bike lights (front and back) I thought I would buy the tried and tested Cateye brand. However, I came across the Knog Boomer USB lights and was sold by the fact the lights were tiny (I can easily fit both in the palm of my hand), light (less than 50g each), are mounted using a silicon band (so no bracket needed) and can be charged via USB (the lights hold their charges very well.) The lights are indeed quite small and light but pleasingly you don't sacrifice any power in the brightness of the lights - both front and rear are extremely bright and feature a few different flashing cycles that you can use.

      Getting the lights on to the bike is relatively straight-forward via the wrap-around band - it's harder to get the rear one on at first but I have gotten used to it. When I first used my lights I was worried that the rear light's band may not hold but it seems to have weathered my fairly bumpy journey to work well enough. I just hope that the silicon doesn't stretch so much that it no longer holds. Be warned for those that have quite side posts - the silicon band may not quite stretch.

      Charging via the USB was a little more fiddly than I would have liked - as small as the bodies are they are still rather chunky in terms of USB slots so, for example, if you have two USB slots you will definitely not be able to use the other slot when charging your Knog Boomer lights. Or if the USB slot is near other items, for example headphones that have been plugged in or even a slightly raised edge, then you will not be able to use that slot for your Boomer. The other slightly surprising aspect is that getting the lights into their silicon casing (which is also supposed to keep the lights fairly waterproof and which functions as the holder to mount on to the bike) is not the slickest and can get frustrating if trying to get the light inside in a rush. Still, for all that it's quite convenient to be able to charge the light via my PC and as the lights seem to hold their charges well enough I haven't really had to do this all that often.

      A note on turning the lights on and off - there is one button to both switch on the light and cycle through the flashing patterns. You should be able to turn the lights off by holding down the button for a few seconds but for some reason mine don't so I'm forced to cycle through the different flash patterns to finally turn it off.

      Overall the lights are a recommended purchase.
